Yes, there are currently problems with terrastorage. The latest Windows nightly is missing too. Sorry about that, hope that normal service will be restored soon but unfortunately there are no guarantees when this will happen.

Terrastorage link is down due to internet provider issues since the 8th of March.
The windows nightly is missing due to build failure caused by an identified root cause.
Terrastorage link is supposed to be up by this Wednesday. Next nightly release, should deliver a Windows build too.

Moving to the new provider seem to have resolved the issues.
Three months of practically unusable Internet service.

Terrastorage got rusty... I got rusty... mumble, mumble...
First attempt to recover from the three month hibernation, brought a new nightly only for Linux architectures.

I'm working on it to gradually restore the service.
I'll keep updating this post so as not to disrupt the peaceful silence of this place.

One more issue is that the terrastorage nightly status page is unreachable.
It seems that terrastorage has been forgotten and network packets cannot find their way to the site. Checking that too.
So for the time being to get the new Linux nightly, go to the GitHub OoliteProject/nightlies Releases.

EDIT 2018-06-15 00:05 (EEST)
Terrastorage is now reachable.
Windows and Mac nightly issues are still under investigation.

EDIT 2018-06-15 18:30 (EEST)
Windows nightly is fixed.
Oolite nightly release has been updated with the Windows binaries.
Mac nightly issues are still under investigation.

EDIT 2018-06-17 11:40 (EEST)
Mac nightly server is in trouble. I escalated this to Jens.
In the meantime, I will try to have Mac-nightly built ad-hoc.
Expect some lag in Mac nightly releases.

EDIT 2018-06-17 18:18 (EEST)
Mac nightly server is reported as fixed for now.
The end-to-end automated process will be verified with the next source code change.

With the Mac nightly engine back online this case is closed.<!-- "Yeah, right!", the penguin thought and with a smile on his face, he rushed back to the engine room.
"Was that a wifi adapter in his flipperpit?!? What's he up to, again?!?" Norby asked.
"Well, you know how them geekz are; can't fly with 'em, can't fly without 'em!" Cody replied.
"Let's hope our nightly engines will survive his 'ideas' this time!" Svengali added and a silent sigh escaped his fatigued chest. -->

EDIT 2018-06-27 22:30 (EEST)<!-- The penguin enters the bridge wearing a blue network cable as a scarf, risking to ridiculously choke himself.
He throws a stare over to the Commanders.
"Gentlemen, T-storage is now riding the µWaves!"
The silver-feathered penguin waddled towards the elevator leading back to the engine room. -->

Windows nightly failed due to nightly engine not being updated with the SDL_events.h change, as this is described in the mouse-wheel handling pull request #294.
I expect the nightly release to be updated with the Windows binaries within the next hour.

The Mac nightly server is still in trouble, so I will manually have a Mac-nightly built and have it ready by the time the Windows nightly is ready.
